Eurybia radula
Also called Rough Aster, Rough Wood Aster, Rough Leaf Aster
Eurybia radula, commonly known as the low rough aster or rough wood aster, is an herbaceous perennial in the family Asteraceae. It is native to eastern North America where it is present from Newfoundland and Labrador in the far northeast of Canada, west to Ontario and south to Kentucky and Virginia in the United States. The low rough aster is also present on the French overseas territory of St. Pierre and Miquelon just south of Newfoundland. It typically grows in wet soils in a wide variety of habitats from bogs and fens to creek shores to ditches. Although it is not considered threatened over most of its distribution, it is imperiled or possibly extirpated over much of its range in the United States. Its flower heads emerge in the late summer to early fall and show pale blue-violet rays with yellow centres.
Eurybia radula is present in every province of Canada east of and including Ontario and is also present on the French territory of St. Pierre and Miquelon. Its northwestern limit is in the northeast of Ontario south of James Bay where it is rarely found. In the United States it can be found in every state from Maine south to Kentucky and Virginia, though it is not present in Ohio and westward. The species is considered endangered by the states of Connecticut, Kentucky, Maryland, New Jersey and New York.
